So, I notice a wall wart 9vdc plug on the back of the Helix control. Uggh. Not what I was expecting. In any case, though, there would need to be power to run all of those beautiful scribble strips.
What is the mv requirement for that connection?
I have a Pedal Power digital so I'm hoping it isn't more than 500mv. If that works then I am golden as I'll use it to power my tuner, line buffer and Digitech drop pedal.
